During exorcise, epinephrine car enhance skeletal muscle glycogenolysis through which of the following mechanisms? Release of Ca
sp2606 [1]

Answer:

The correct answer will be option- Increase in cAMP

Explanation:

Epinephrine is the hormone which is secreted during the stress conditions which prepares the body for fight or flight response. The epinephrine for flight activates the cAMP pathway in the muscles which leads to the activation of glycogenolysis process.

The epinephrine hormone binds the receptors in the muscles which convert ATP to cAMP. The cAMP bind to inactive PKA and activate it. The activated PKA converts the Phosphorylase b which activate the glycogen phosphorylase a which converts the glycogen to glucose 6 phosphate.

Thus, option- Increase in cAMP is the correct answer.

An _____ is a drug that mimics or increases a neurotransmitter's effects, whereas an _____ is a drug that blocks a neurotransmit
alexdok [17]
Agonist/antagonist
 Agonist are drugs that bind and activate a receptor with effecting the response.If the effect results in maximum response it is considered as full agonist. However if the drug that binds to the receptor results only into partial efficacy in relation to the full activation of the receptor, this is considered as partial agonist.

Antagonist are drugs that blocks a biologic response of a hormone or another drug. They usually have affinity to the receptors but has no efficacy. This drug will just inhibit the activation of the receptors by the aganist.

In garden pea plants, purple flowers (P) are dominant to white flowers (p), and full pod shape (F) is dominant to constricted po
kifflom [539]

Answer:

The phenotypes are as follows

Purple, full- 9

Purple, constricted- 3

White, full- 3

White, constricted- 1

Genotype of parents are PpFf, each produce the following gametes: PF, Pf, pF and pf.

Explanation:

This is a dihybrid cross involving two distinct genes. One coding for flower color and the other for pod shape. The allele for purple color (P) is dominant over the allele for white color (p) while the allele for full pod (F) is dominant over the allele for constricted pod (f).

In a cross between two heterozygote parents i.e. PpFf × PpFf, each parent will produce the following gametes: PF, Pf, pF and pf. Using these gametes in a punnet square (see attached image) the following 16 offsprings will be produced in a phenotypic ratio: 9:3:3:1

Purple color, full pod- 9

Purple color, constricted pod- 3

White flower, full pod- 3

White flower, constricted pod- 1
